AS12716 announces 42 IPv4 prefixes covering 40,704 addresses and 2 IPv6 prefixes.

About this network

Netnames that map the fibre rollout street by street, and one that still says GPRS.

What it's used for

• Fixed and mobile access in Bulgaria. 40,704 addresses in 42 IPv4 prefixes, two IPv6 prefixes, and one observed BGP neighbour.

Notable

• Two blocks are named for the fibre plant that serves them: GPON-VelikoTarnovo-South-1 and GPON-SofiaSouth-2.
• 78.90.188.0/22 is KRASNO-SELO-SOF, a district of Sofia, registered through Megalan Network hostmaster.
• 85.118.80.0/22 is MobiltelGPRSNetwork.
• The older allocations carry the previous brand: BG-MTELNET-20050404, 20120123, 20120821.
• Two sampled addresses answered under mtel.net.

Interesting

• GPON is the passive optical technology used to run fibre to homes, and naming the blocks after the districts they serve turns the registry into a deployment map. Anyone reading the records learns which neighbourhoods were cut over and in what order, which the operator publishes nowhere else.
• GPRS is packet data over 2G, a technology from the late nineties. A live block still carrying that netname means the addresses were assigned for mobile data when that was the only kind, and were never renamed as the network went through 3G, 4G and 5G underneath them.
• One observed neighbour against 42 prefixes marks this as a member of a larger group rather than an independent operator. The mobile arm announces its own space and reaches the world through a sibling network, which is an accounting boundary made visible in BGP.
